As shown in the drawings:

The mechanisms of each of the three sta es of the machine are mounted eitherartia y or entirely submerged in water wit iin suitable tanks for the purpose, and for this purpose a tank 1, is provided for the mechanisms of the first stage and is separated from a tank 2, of the secon stage, bly a artition 3, such that the level 0t theiiqui in the second stage is higher than that in the first stage, but 1s ernntted to flow over said artition into tie first stage tank. A ta 4, for the third and last sta is separated from the tan 2, of the second stage by means of a partition 5, which is of a height such that the liquid in the third stage tank is at :1 hi the second sta an oversaid Cpartition from the third adage into the secon stage tank. Mounted upon the floor of the tank 1, of the first stage of the machine, are -a different heights, each one of which is curved along the arc of a circle on its upper side and is provided with rollers f.

A hollow cylinder 8, provided' with grooved or channeled track members 9, extending circumferentially around the exte is a view taken on line 1717 of rior thereof, rests upon the rollers of saidstandards in a slightly inclined position with the rollers trackin in said channel members, so that the cy inder may bero tatcd and. is held supported u on 'said roll ers. Uprights 10, are maunte near the entrance end on the sides of the tank 1, and

of the machine.

er level than that in is permitted to flow" plurality of standards-6, ofbe ing means are connected by means of a cross piece 11, and similarly u ri ts 12, are mounted near the other en 0 said tank, and are connected by means of a' cross piece 13. -A transverse shaft 1-"l is journaled on said uprights 10, a in suitable bearings for the urpose, and at itsouter end is rovided wit a drivin pulley 15. Near t 1e other end of said aft a bevel pinion 16, is keyed thereon, which meshes with a bevel pinion 17, secured on the end of a shaft which is journaled on said cross, piece 11. The shaft which carries said bevel pinion 17, is provided at its opposite end with a pulley or sprocket wheel 18, around which is trained a chain or cable 19, which: is also trained around within a suitable grooved member 20, on the perishe of said cylinder 8. The interior 0 sai cy inder 8; is' rovided with helically disposed scraping ri 21, which also assist in moving the carcass therethrough.

An entrancechute W, is mounted on an incline at the forward end of the tank 1, and communicates into the end of said c linder 8, whereby caresses may be easily introduced into the machine. As clearly shown in Fig. 5, theinclined c linder 8, is mounted in such a position on standards 8, as to be partially-submerged in the water within the tank so that a carcass passi throalligh said cylinder is at all times subject to plenty of acaldi water.

Mechanism 1! provided or conveying the carcass from the tank of the first stage into the tank of the second stage, over the partition 8, and this. consists of a conve er 23, the' lower end of which is trained shout a roll 2%, jmlrnaled transversely in the tank 1, and upper end of which is trained about a re '1, and driven'by means of a belt or chain 26, which engages around a suitable pulley on the end offsaid roller 25. For the par of driving said belt 26, uprights 27, are provided on each side of the machine and are connected b means 'of' a transverse cross piece 28. djacent said cross piece; -and onrnaled Jill suitable hearings on said uprights, is a shaft 29, on one of its'ends provided with a drivi pulley and also having a belt pulley 1, around. which said It 26, is engaged. A valved spray pipe 32,

supported at one of its ends it n the cross piece' 18, extends thmu sai cylinder 8, along the upper side of t e interior thereof.

In the'second stage of the machine mechanism is provided not only for conveying the carcass alonmbut for subjecting the same to scrap'in and deh'airing means which move --vert1cal y, causing rotation of -the corona -npon its carrying means whereby the carryis also brought into' operation as a scraping mechanism. For this purpose twomarrying means are provided, one mountedlongitudinally on each side of the 130 journaled above said partition 3, 5%

cry thereof, adapted to scrape the carcass and assist in eonveyin the same forwardly through the machine. igidly secured upon ouch of-said respechvc transverse shafts T5, and T6, are rolls 83 and 81, respectively,- one pair disposed on each side of said partition 71, and trained about each of the rolls 83 and 8+, 01: each pair is a belt 85,'carrying a plum lit of flexible heater or looped scraper mechanisms S6, which more linearly between the roll 81, and said stationary partition. The drive for said respective belts is 'imparted 'thercto through the shaft 75,

-which has a pulley 87, secured on one end thereof and trained about which is a cable 88, which is also trained about a pulley 89, secured upon a transferse shaft 90, which is in turn driven in any suitable manner through a pulley or sprocket wheel 91, secured thereon. Said transverse shaft 90, 1s

journal-ed upon uprights 92, mounted on each side of said tank at, said uprights being connected by means of a cross piece 93, extending over the top thereof. Auxiliary scrap-- mg rolls are also provided to couct with the large rolls S1, and for this purpose brackets- 91, extend inwardl from the side walls of the tank on the sides thereof, and downwardly to said bearing members 7-3 and 74,

. and journaled therein are shafts 95 on each of which is mounted a roller 96, with scraper elements 97, thereon. For the pnrpose'of rotating said respective rolls 06,- sprocket wheels 98, are provided on' each' of said shafts 95; and a large sprocket wheel 09,-.is also secured on each of 'said shafts 77, permitting a chainv 100, trained thereabout. to-

transmit a drive between said respective shafts, Uprights 101, also mounted inthe dischar'ge end of the machine on each side of the tank 4, and are 'c'onnectedat their upper ends by means of a cross iece 102. Journaled-on said uprights 101, is a shaft 103, ndapted'to be driven inany suitable manner by means of apulle or sprocket 104,

.- secured thereon. A; sproc 'et wheel 105, is secured on sandshaft 103, ad scent oneof the uprights 101, and similar y. a sprocket 106 is secured upon said shaft .79, and a chain 107, is trained over said respective sprockets --to drive the shaft 79, from the shaft 1031 A channel shaped floor 108 is built transversely across the machine at the discharge and of said respective-rollers and same over a hook 109, a number of which are secured upon the crossbars '110,of I. slatted conveyor. Said conveyer is-trained about rblls.111, 112, 113, and114, said roil s 112, 113, and 114 beingmountedupon suit-';

able upri ts 115; and 116. The roll 111, is journal brel to iii-1.1a his the; ma hook'sthe onshortupr' hts"117,'one disposed on each side of the disc urge end of the tank A drip 'pan 118, is disposed beneath the horizontal run-of saidconveyer' to receive the water draining from thccarcasses, per- 1" me to floiubackin'to said tank 4.-. e

The operation is as follows: The carcass is introduced into the inachane upon the inclined chute 22, entering the tank 1,- of the first stage of the operating mechanism and slides downward'into the intenor of the rotating cvhndcr 8, whereupon the sc'ruperfrlbs 21, serve'to assist lll moving the carcass therethmugh'an-d at the 'sa'me time-remove superfluous dirt'and hairf-from the eu'|'c'ass,.the \vut'crin whicli said cylinder is partiallysulnnorged washing the carcass,

as well as scalding the same during its progress Immediately afterits passage through said cylinder 8, the carcass is-conreyed into the tank 2, [iv means of said conveyer 23, and is introduceduponcither oneof the two inclined scraper conveier mechanisuis; which move longitudina 1y within said-tank Owing to the-inclination of the conveyer the carcass is caused to'rcst against-and is partly supported-by the vertlca'lly moving dehuiring mechanisms 58 and 59, which alsocause the carcass to rotateon the -c-. i'rrying scra 'ier elements 51,- which thus assist in-dehairing the same.

Practically; all. the hair is nemovedfrom the carcass in" the secondstage of the ma chine, and after its -f passage therethrough,"

the carcass is conveyed into the third stage, or the tank 4, by-mcansof a. conveyor 67 on which tho curcnsa' isdischarged from sai inclined 'conlveyingmechanisms 51. The

camassintmduce'd into the third stageof the machine. is .positioncd longitudinally between one of thellarge rolls 81, and the stationarypartition, and is causedutorotate 1".
